If a lateral-to-medial load is applied to the foot, a counteracting moment is produced at the knee joint in a lateral-medial plane, which stretches the lateral collateral ligament and the cruciate ligaments. Estimate the moment produced by cruciate ligaments to that produced by the lateral collateral ligament. Use the force-deflection characteristics of the ligaments in your solution.

Note: Communicate with class notes. MC=FCLC and ML=FLLL
From force F-displacement D, F=kD (k: rigidity coefficient)
